Introduction
In the hydraulic system, power is by means of a closed loop pressurized liquid to pass and control. This is both a liquid lubricant, but also work
The rate of delivery media.
Reliable system performance requires cleanliness of the liquid medium can be controlled. Liquid medium particle contamination qualitative and quantitative determination
Fluid requirements during sample collection and accuracy of the determination of having carried out the nature and extent of pollution.
Determination of contaminated liquid weighing method requires weighing the mass per unit volume of oil suspended solids. The method uses filters to collect samples
Insoluble particles, liquid particles measuring system to achieve pollution.
Hydraulic fluid contamination
Determination of particulate contamination using the gravimetric method
1 Scope
This standard specifies the determination of the hydraulic system of the working medium particulate contamination two weighing method (double and single membrane filter method). Double filter method
To obtain a more accurate test results.
This standard applies to the detection of particulate contamination of the hydraulic system is greater than the working medium 0.2mg/L of.

Principle 4
Under vacuum, through a filter or membrane overlapping two same known volume of liquid filtration. When using a membrane filter
After the filters have increased the quality of the content of the equivalent volume of liquid impurities; when using two filters, filter membranes, respectively, these two sheets increase quality
An amount equivalent to the difference between the content of the volume of liquid impurities.
